Well,in fact there is only one Aikido.The different so-called-styles is nothing more than different approaches or choices by various teachers of something that in essence has the same basic principles and set of techniques,all the developement of one man:O'sensei Morihei Ueshiba.

If one learns those basic principles then the application can be according to the situation at hand(if we are talking for a real fight) or the synthesis of the dojo and even the mood of a speciffic day(if we are talking for a lesson).

The proof that so-called-styles are in fact non-existant, lies in the mere fact that teachers of the same "style" or organization often seem to be having a very different approach in Aikido among each other.So don't worry about it,just keep on practicing and...welcome aboard!
